In this work design and development of a micromachining system which can perform on non-linear contoured surfaces is studied using a parallel manipulator system. Laser micromachining system is designed and assembled including a nanosecond Q-switched pulsed fiber laser, a 6-DOF hexapod manipulator, a granite table in order to absorb vibrations and an external cabin system to isolate the whole system for safety and health issues. Performance characteristics of micromachining devices mainly determined by precision and characteristics of each individual components of the system. Very complex shapes can be scanned in various way using the extra degree of freedom in the system.

The main motivation in this research is the improved surface quality in already manufactured parts. In many cases the shape and the feature of the finished product requires additional degree of freedom to be scanned with a laser system.
